Purchased a Motohorn 3.0. “No mechanical or electrical knowledge is required”. Yeah. Ok. I know where I want to mount the horn, relay and compressor but, can’t find/don’t know where to look for the existing horn wires without taking the truck apart, which I’d rather not do. Any ideas?IMG_6893.jpeg

So I found my horn wire by accident when doing my remote start upgrade. From underdash it's #23 (directly opposite of #11) on C1. I'm apparently dyslexic and confused them. It was gray if I recall correctly.

Thanks, Bill but, gotta be honest with you so, don’t judge when I ask. This “C1” you speak of; I’ve never looked under my dash. (Raining at the moment so, maybe tomorrow) Are things labeled clearly so a novice, such as myself, can figure it out? And, I suppose “ground is ground” wether it be to frame or battery?

My bad . I'm a noob too and wanted to sound knowledgeable lol. It's tucked away but if you search forum for remote start there are great diagrams and such. I found out after completing my I stall that their is another wire in the front left engine bay you can tap into. I'll fi d link to post
